PromptOT

What it does

Every team building with LLMs hits the same wall: prompts hardcoded in the codebase, no version history, no roll back when something breaks production. PromptOT fixes this. Build Prompts automatically in typed blocks. Version every change. Evaluate across GPT-4o, Claude, and Gemini. Ship via one API call - no deploy, no PR, no downtime, no switching on multiple tabs. Change a production prompt in 10 seconds without touching your codebase. Your code has GitHub. Your prompts now have PromptOT.

Manage, version, evaluate, and deliver AI prompts to your applications. Compose from typed blocks, version safely, and deliver via API.

One platform for every production prompt, delivered via a single API call. Every model call in production depends on prose, and nobody knows which version is the good one. When something breaks, you roll back code but the prompt is gone. PromptOT is the CMS prompts deserved. Author in typed blocks, version with real history, evaluate against saved test cases, and deliver to any model without changing your app. Everything teams need to author, version, evaluate, and deliver LLM prompts in production. All in one workflow. Six first-class block types: role, context, instructions, guardrails, output_format, and custom. Each is typed, validated, and versioned independently. Every change is a…from promptot.com

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
